Method and apparatus for producing carbon black in which a first mass of hot combustion gases containing hydrocarbon feed is passed centrally and counter currently to a second mass of hot helically-flowing combustion gases whereby the hydrocarbon feed is pyrolytically decomposed to carbon black which is removed from the downstream end of the reactor and a portion of the hot combustion gases substantially free of carbon black are removed through ports in the upstream end of the reactor.
